    Another theory :-)

    Is there anyone experienced with samsung unlocking with codes?Wat i hav in my mind is there are som network personlization codes in samsung which we use with original SIM on which its locked to And we manually personalize to certain network with
    *7465625*638*00000000*00000000#
    where in the above code last 8 digits are the nck code which we hav given

    than we use

    #7465625*638*00000000#
    ^accept the code as 8 zeros^

    hence phone unlocked and we use this trick in many samsung phone which are not possible to be unlocked in anyother way yet

    so my point is can we use som codes similarly with the accepted sim i.e:AT&T ,O2,T-MOBILE are prespecified as accepted networks somwhere in phone?

    Omaar ...you won't be left with a brick. I too thought this may be the case. When you get to the point of no baseband, don't try to unlock it. Just get the firmware with in cahoots with the baseband. My theory is to show no baseband and to then restore with firmware...hopefully by not showing any baseband that the firmware will restore to the original as it has no reference point. Again not tryig to downgarde just saying that hey there's no baseband so now what? Sasser sounds like he's exactly where I'm talking about.....Forget about the downgarding process...we are actually removing not donwgrading. The 2 are completely seperate. The fact that it's missing allows us to replace. If it's still there I beleive that we cannot downgarde etc. Remove it!

    So youre saying that if we somehow break the baseband (that means if we somehow corrupt it) we can then put any firmware we want and it will upload the baseband of that firmware?
    That should be logical. But anyone has an idea how to do it?

    Does anyone actually read in these forums?
    Even if we could delete the baseband we cant add our own baseband(hacked) because the bootloader checks if the baseband you want to "upload".
    So if you don't have a digitally signed baseband the bootloader is gonna say say "F U!"

    So if we hope for a soft unlock we should either orient our attempts on spoofing a digital signature, or reversing the iphone official unlock process.
    But for the second to work we need someone to sniff the traffic when unlocking his iphone in France.

    There was an attempt to raise money to get a French iphone unlocked, but I guess that attempt ended with someone having a free unlocked french iphone

    AFAIK if you want to corrupt your baseband your going to need to have write permissions to it. If you have write permissions you could just write a new baseband on it anyway. The current problem is that it is not currently possible to get to write anything to the baseband.

    The dev team are smart people - if there was a trivial way of getting around this problem I think they would have already found a solution. Of course, there may very well be some unfound exploit which will do what is needed, but surely it's likely to be a software implementation bug as opposed to an algorithm flaw. Corrupting the baseband isn't going to be so straightforward. The guys in apple, I'm sure, some of them at least are also pretty smart, and are quite unlikely to leave a huge security hole in their software - esp seeing that it's already had a few releases, with better security each time. Implementation level bugs are quite common - but the baseband itself is quite small so there is less room for error.

    Another intersting thing is so called (Stealth Sim) which actually not a sim but a eeprom which contains the fake IMSI AND ICCID of the preaccepted networks thats why 3 diff. stealth sim available for three diff networks
    1=(CONTAINS IMSI Tmobile for germany)
    2=(CONTAINS IMSI O2 for U.K)
    3=(CONTAINS IMSI AT&T for USA)

    so my question is how he has done all and executed coorectly with eprom? And does it give us a way to code a utility which can work in 1.1.2 and can fake a imsi and iccid?I mean before putting a sim we run that application in phone than put any network sim in it?

    Well, thats what the appelsaft program for the TurboSIM does AFAIK. The StealthSIM is just a copy of this.

    This is a baseband issue - You could set any IMSI/sim information in the baseband if you could write to it.....then again if you could write to it you could use AnySIM in theory.
